Here's some more info Joe
My Blitzortung.org station 1162 reboots daily.
It is located at 42 degrees latitude.
GlobalTop PA6H GPS module. The antenna is a Motorola patch in
the attic, looking through wooden boards and tar shingles. I
have the antenna against the underside of the roof, tipped to
the South. There are power lines on the South and East sides of
the house. On the North side of the house is an 17 meter high
tower with guy wires and HF inverted V antennas. Lots of
multi-path. My H-field loops are made from old, quad-shielded
Thick-LAN cable, 3 turns, 1.5 meter diameter.
The controller has been running 18 hours so far today and there
is a heavy cloud cover today. Here are current stats:
